"What reduces one race to starvation stimulates another to harder work. All the great civilizations of the past became decadent because the originally creative ... race died out, as a result of contamination of the blood. The most profound cause of such a decline is to be found in the fact that the people ignored the principle that all culture depends on men, and not the reverse. In other words, in order to preserve a certain culture, the type of manhood that creates such a culture must be preserved, but such a preservation goes hand in hand with the inexorable law that it is the strongest and the best who must triumph and that they have the right to endure. He who would live must fight. He who does not wish to fight in this world, where permanent struggle is the law of life, has not the right to exist. " - Mein Kampf
